TURBINE.

Application filed January 26, 1921. Serial No. 440,065.

To all whom 'it may concern:

Be it known that l, JOHN GORDO-N SUM- Mnns, a citizen of .the United States, residing at San Diego, in the county of lSan Diego and State of California, have invented ya new .and useful Turbine, of which the vfollowing is a specification.

rThis invention relates' to a turbine, -one of its objects being to provide a simple strlucture of this character adapted gto `:be operated by steam, air or gas, there bei-ngsimple and efficient means whereby the flow of pressure into the stator can be .so controlled as 'to drive the rotor either clock-wise or counterclockwise as desired.

A still further object is to provide a rotor having a novel yform of sinuous impact receiving channel provided with regularly spaced cut-offs whereby, during the actuation of the rotor, intermittent impulses are transmitted thereto from nozzles vdischargl ing int the stator.

it further object is to provide a structure of this character in which are lprovided sealing rings or washers readily adjustable and which engage opposed faces of the rotor, thus to prevent leakage l`between the rotor and the walls ofthe stator.

W'ith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and .arrangement of parts and 1n the details of construction hereinafter vdescribed and claimed, it. being 4understood that, within the scope .of what is claimed changes in .the precise embodiment of the invention shown can be made without .departing from theI spirit of the invention.

ln the accompanying drawings the Vprel'erred form of the invention'hasbeen shown.

In said drawings A Figure l is a View .partly in elevation and partly in section of a turbine embodying the present improvements.

Figure 2 is ,a section on line 2 2, F igure 1. l

Figure 3 is a plan View of a motor vincluding a high pressure and a vlow pressure turbine, the connections between the two stators being illustrated.

Figure 4 is an enlarged section through a portion of the stator and showing the adjustable yieldingly pressed sealing ring.

Referring to the figures by characters of reference 1 designates the base of a cylindrical stator 2 one head 3 of which can be made integral with the 'circumferential vportion of has an annular groove or channel 6 arranged l Opposite@ 't0 ZUIClCOHSSPODdiDg withrt'he i the stator if preferredand :is proivided, at its cov channel 3 and 'in both channels are inorvably n mountedsealing Vrings Apfreferarl'ily split as shown atS and these rings are provided with backings consisting of leafl springs 9 j in which are swiveled adjustingA screwsLO.

These screws entend through the outer walls l Y of the channels 3 and 6 and 'by means thereof the tension of the' springs 9 :can loe-varied so 'that the springs will press against the rings 7 with any desired degree of pressure. Each of the screws 10 can be a lock nutas indicated at 1 1. yFormed von the periphery of thestator, preferably adjacent the 'top thereof, are spaced pairs of ribs or projections 12 having tapered openings 13 inner surface of ',.thev

provided "with therein in communication with threaded bores 14 .extending through the wall of the stator. ln each of .these "bores is arranged a'threaded nozzle 15 having a tapered discharge end seated within the .tapered `porclined oppositely` to the' nozzles o-f .the other pair and the nozzles of each ypair are .tangentially disposed relative to an imaginary circle within the stator.l Extending across the ribs 12 orf each pair'is a cut off plate 1S having openings 19 registering with the outlet .ends of the :bores 14', .each-,of Ithese plates bridging the spacesy between the ribs of the engaged pair and the .ends ofthe' plates .being offset outwardly and lsecured to the wall of the stator as shown at 20.

Arranged 'within the wall .of the 'stato-r and between the uppermost nozzles of :the two pairs is an outlet port 21 in communication with an outlet pipe 22. Y

Journaled within the middle portions of the heads'3 and 4 is a shaft 23 to which is keyed or otherwise secured a rotor 24 arranged-within the stator and fitting snugly against the two heads. The peripheral porv of the stator as shown particularly in Figure l but is adapted to work upon the inner faces of the cut ofi' plates 18. The rings 7 are pressed against the sides of the rotor at its periphery and serve to seal the sides of the spaces between the rotor and the stator. This is clearly shown in Figure 2.

Thek rotor is provided in its periphery with a continuous sinuous groove or channel 25 and at regular intervals this channel or groove is bridged by cut ott plates 26 the outer surfaces of which are iiush with the periphery of the rotor. The plates are so proportioned that the distance between the advancing edge of eac-h plate and the opposed edge thereof is slightly less than the distance between the two outlets 19 of each plate 18. rlhus itwill be seen that during the operation oi the rotor each cut. o'l plate 26 will extend'across one of the outlets 19 of a pair` whilethe other outlet 19 is open but as the cut ofi' plate passes across the second outlet port 19 the iirst one will become exposed. Thus the pressure is delivered alternately through the two outlets i9 of the active pair and caused to be projected intermittently in jets into the sinuous groove 25 so that thevrotor is given intermittent impulses and caused to rotate at a high speed. f l

rllhe flow of steam, gas or other like propelling medium tothe various nozzles is controlled by valves as indicated at 27 in Figure 3. v 1 y Obviously by closing one of the valvesV 27 the motive fluid will be directed solely to the set of ports controlled by the other valve and when delivered through the nozzles which are thus left in communica-tion with the source of pressure the jets of steam, gas or thelilre will be directed intermittently as heretofore described and cause the rotor to operate in one direction. By operating the valves so as to direct the pressure to the other pair 0i' nozzles, the operation of the rotor will be reversed, as will be obvious.

if desired two Aturbines can be combined as shown in Figure 3 so as to provide `a high pressure turbine A and a -low pressure turbine B, the exhaust pipe 22 extending from the high pressure turbine to the branch pipes 28 leadingto the delivery nozzles ot' the low pressure turbine.

. What is claimed is:

l. The Icombination with a stator having two pairs of nozzles discharging thereinto, the nozzles of one pair extending in one direction and those of the other pair in the opposite direction, said `nozzles being tan'- stator and having a continuous sinuous channel in its periphery and cooperating means carried by the stator and the rotor whereby the operating fluid is delivered alternately through the nozzles of the active pair and caused to be projected intermittently in jets into the sinuous groove of the rotor, thereby imparting intermittent impulses to the rotor and causing it to rotate vat high speed in its perimeter. i y

2. The combination ot a stator including heads and having an annular channel at its margin on its inner tace, spring seated sealing rings closing said channels, spaced pairs of ribs on the inner iaceot the periphery of the stator, said ribs having tapered openings, those oi one pair of ribs extending in a direction opposite to those in the other pair, the wall of the stator having threaded bores communicating with said openings, nozzles mounted in said bores and openings, the nozzles oi each pair being tangentially disposed relative to an imaginary circle within the stator, a cut oiplate extending .across the ribs of each pair and having openings registering withr vthe nozzle openings, said plate spanning the. space between the ribs of each pair and having their ends offset outwardly andsecurved to the wallor" the stator, an outlet arranged between the two pairs of nozzles, a rotor spaced peripherally from the stator and working on the cut oli' plates thereof, the rotor havinga sinuous channel in its periphery, cut off plates 'bridging said channel in its periphery,`cut oil plates bridging said channel at regular `intervals and of a length slightly less than the distance between the outlets in the cut oil' plates of the stator, whereby intermittent impulses are imparted to the rotor by the alternate vdelivery of the actuating fluid through the activepair of nozzles.

,ln testimony that .lclaimthe foregoing as my own, l have hereto aiiixed my signature inthe presenceot two witnesses.
